-guard rail 1 which has inturned curved end portions 8 and is of segmental contour in vertical The length of rail 1 will be as desired and is sodisposed relative to a side 9 of roadway I I) -that its convexf'ace II will be arranged inwardly adjacent to such side. lThe rail 1 is im- ,perforate The rail 1 is clamped to a set oi spaced resilient suspension structures I2. Eachstructure I2 is secured at its lower end to the front of a vertical support I3 anchored in the ground inwardly adjacent to roadway side 9. The lowe'i` ends of structures I2 are secured to the supports I 3 in proximity to the ground level. i

The structures I2 are of like form and'each includes an upstanding resilient section I4 formed y froma strap of metallic material Yhaving a vertically disposed lower end part 'I5, an intermediate part I6 extending upwardlyfrom the upper end of part I5 vat an outward inclination and an upper end part I1 of segmental contour inlengthwise section having its convex face bearing against the concave face of rail 1. The part I1 is eccentrically disposed with respect to the part I6 and i a support I3. The top edge of part I1 is notched, 'as at I8. The part I1, in close proximity to its point of mergence in part I6, is formed with an opening I9. The part I5 is provided with a plul rality of openings 2Il. The part I5 abuts the front of a support I3 and has its openings 2U :register with the outer. end of openings 2I formed transversely of support I3. `Bolts 22 extend through the registering openings 20, 2I and have their.

heads 23 abut the front face of part I5. The bolts 2 2 extend beyond the rear face of support I 3 and carry clamping nuts 24 which coact with the heads I23 for clamping the section I4 to support I3 to provide for the parts I6, I1 to be arranged in spaced relation to the support.

Each Asuspension structure I2 also includes a clamping section 25 formed of a strap of metallic material of less width than that of part I1 of section I4. The body part of 'section 25,' indicated at 26, corresponds in length to that of part I1 the convex or front face II of rail 1.

of section I4 and is curved lengthwise to correspond to the curvature of part I1 of section I4.

The concave face of body part 26 bears against The body part 26 is of greater length than the width of rail 1. The section 25, at the top of body part 26, is

formed with a rearwardly extending angle-shaped flange 21 formed of a horizontal leg 28 and a vertical leg 29 depending from the inner end of leg 28. The body part 26 in proximity to its lower end, is formed with an opening 30. The body part 26, in transverse section, is of` segmental contour. When section 26 is in clamping position the leg 28 of ilange 21 extends through notch I8 and seats upon the top edge of rail 1, leg 29 bears against the upper portion of the concave face of section I4 to form a quick detachable connection. The lower end of body part 26 depends below the bottom edge of rail 1 to an extent to have opening 38 align with opening I9 of section I4.

Each suspension structure I2 further includes a holdfast means for connecting sections I4 and 25 together in a manner to xedly maintain the 2,030,7@2y Figure 20 is a perspective view of the resilient` body part 26 of section 25 in clamping engagement with the rail 1 and the part I1 of section I4 to tightly bear against the inner face of rail 1 whereby the rail 1 is prevented from bodily shifting relative to any one of `the structures I2. The holdfast means consists of a bolt 3I extending through the openings 30, I9, having its head 32 bearing against the outer facev of body part 26, its shank projecting from part I1 and a clamping -nut 33 coacting with head 32.

The manner of setting up the suspension structures provides for them suspending the guard rail eccentrically in spaced relation relative to the front of the supports I3. On loosening the bolts of the suspension structures the guard rail 1 may be readily adjusted bodily lengthwise with respect to the set oi spaced supports I3. The suspension structures provide cushioning means for the guard rail when the latter is impacted by a vehicle. l

u Referring to the modiiled form shown in Figures 7 to l0, the guard device includes a guard rail 34 of the desired length and width which is not curved transversely as is the rail 1, a set of spaced opposed vertical supports 35, only one shown, to be anchored in the ground and a set of resilient suspension structures 36, only one metallic cylinder 39 open at each end and split from its upper to its lower end to provide apair of end edges 40, 4I. The parts 42, 43 of the body of cylinder 39 bordering the edges. 48, 4I respectively are arranged in overlapping relation. The upper portion of parts 42, 43 are provided with registering openings 44, 45 respectively. The lower portion of parts 42, 43 are formed with registering openings 46, 41 respectively. 'I'he openings 44, 46 are to register with the front end of the openings 31 in a support 35. The top edge of the front part of cylinder 39 is formed with a transverse notch 48. V'Ihe front face of the front of section 39 is positioned against the rear face of rail 34. v

Each suspension structure 36 also includes a clamping section 49 of inverted yoke-shape form having its top 50 seated in notch 48, its iront side 5I bearing against the outer face of rail 34 and its rear side 52 bearing against the inner face of .the front of cylinder 39, its top 50 seated in the top edge of the rail 34 and its sides 5I, 52 depending below the bottom edge of rail 34 and cylinder 39. The sides l5I, 52 are resilient and are formed in proximity to their lower ends with aligning openings 53.

Each suspension structure further includes a holdrast means for tightly securing the rail 34 and sections 38, 49 -in clamped abutting relation whereby the rail 34 is prevented from bodily shifting relative .to any one of said structures. 'I'he holdfast means consists of a bolt 54 extending through the openings 53 having its head 55 bearing against thfront face oi side 5I of section 49 and carrying a clamping nut 56 to bind against the rear face of side 52 of section g shown, and which are adapted to be anchored in the ground adjacent a side of a roadway. Each support |21 will be provided adjacent its upper end with an opening |211i extending from its front to its rear face as shown in Figure 18. There is to be associated with the front of each support |21 a resilient suspensionistructure |28. The structures |28 are for the purpose of resiliently suspending a .straight guard rail |29. The

resilient suspension structures |28 are of like form and each includes an upstanding resilient section |30 of substantial oval contour in side elevation. The section |30 consists of a single length of strap metal bent in a manner to form a vertically disposed rear part |3l, oppositely curved upper and lower parts |32, |33 respectively arranged in superposed spaced relation and extended outwardly from part I3 an inner front part |34 depending from the outer end of part |32 and an outer front part, extending upwardly from the outer end of part |33. 'I'he latter is of greater length than part |32. The part |35 is of materially greater length than and abuts the outer` face of part- |34. The part |35 is of greater length than part |3| and extends above the part |32. 'I'he part |3| has a central opening |36. 'Ihe section |30,` at the point of. jointure of part |33 with part |35, is formed with a downwardly inclined opening |31.

part |35 is formed with opposite downwardly inclined top edge ,portions |39 leading from the side edges of notch |38 to the side edges of part |35.

Each resilient suspension structure |26 also includes an upstanding clamping section |4| formed from a strap of metallic materialot less width and length than that of the strap from which section |30 is formed. The section |4| consists of a vertically disposed straight intermediate portion |42, a rearwardly directed angle-shaped upper end portion formed of a horizontal leg |43 and a vertical leg |44 depending from the rear end of leg |43 and a depending rearwardly curved lower end portion |45 formed with a downwardly inclined opening |46 aligning at its inner end with the outer end of opening |31. The leg |43 extends through notch |38. The leg |44 opposes the inner face of the upper portion of part |35 of section |30. The rail |29 is interposed between sections |30 and |4|. The bottom edge of rail |29 is arranged above openings |31, |46. The angle-shaped upper end of 'section |4| connects the latter to the section |30. Extending through the openings |31, |46 is a downwardly inclined holdfast means |41,

. which coacts with the angle-shaped upper -end of section |4| for securing the rail |29 to a resilient suspension structure |26. The lower inner corner of the rail |29 seats on a point of that part of theholdfast means larranged between the sec- 4structure |48 is of a different formvthanthat of section |30 of structure |28. The section 49 includes a vertical rear part |50 having an opening |5|, a bottom part |52 and a single front part |53 extendin 'wardly .fromthe outer end of The top of'part |35, centrally thereof, isformed with a notch |38.
